' 2 Claims. '(Cl. 72561") C The invention relates to truss beams, as described in the present specification andillustrated inthe accompanying'drawings that form part of the same. I

The inventionconsists essentially in the composite blocks, the concrete beams andtheir joint members in the construction of building sections; as pointed ,out in the claims for novelty following a detailed description of the blocks, the beams, the-fasteners andthe sections.

- v'Ihe objects of the invention are to eliminate the great expense of labor and forms utilized at the actual work, and in place furnish the beams and if necessary the walls, as well as fitting a particular block to foundation work and meeting all the exigencies of the Work in hand; to .facilitate the erection-of the concrete type of dwelling or other building parts direct tothe'builder and simply putting them together which last act is accomplished in the joints forming permanent partsof the beam and interchangeable throughout, thus enabling the builder to proceed with his constructionwithout the necessity of having highly skilled men, merely what may becalled intelligent laborers; to maintain the highest eiliciency in the finished house and insure openings and passages for every modern convenience besides enhancing the ap pearance of the finished structure; and generally 7 to provide in cement and concrete construction a work a truss beam having the truss rods disclosed in registering recesses and matching in said recesses for riveting or other fastening in order to bring the ends together in assembling at theparticular job;

Referring to the drawings, the various concrete sections are connected by bolting 'steel'bars together. Thesteel bars I5 and it are laid invarious concrete units in the factory, and have their ends I! and I8 projecting from the top, bottom or side of the unit according to the use made of said unit, the projecting ends ti" and iii are made wider and heavier to insure a strong connection.

The bolt holes P9, 20, 2| and- 22 aremade. in

bolts having the nuts 25 and 2'5. 4 Figure 2 shows a concrete beam Zl with the bolting recesses 28, 29, and 3|, the connecting ends of thesteel bars l5 projecting from the beam 22 in said recesses '28, 29, 30 and 3| and ready to: be bolted to the'steel bars I 6, projecting from asimil ar beam 32 shown in Figure 3. The steel bars can be riveted or welded together imstead of bolted and the concrete beams can be column, floor or roof sections.

In Figure 4 the wall sections 33 and 34 are connected to the wall sections 35 and 36 by bolting the projecting bar 31 of the wall sections 33't0- the projecting bar 38 of the wall sections 35, and

the bar 39 of the wall section 34 to the bar 40 of the wall section 36, at the corner joints the bars 38 and 46 are bent at right angles over the bars 37 and 39 and bolted with the bolts 40 and 4| and the nuts 42 and 43 respectively. The partition wall or inner wall 44 is connected to the Wall sections 35 and 36 by bolting the projecting T-bar from said wall 44 to the bars 38 and 48 of the wall sections 38 and 40.

In Figure a bracket 45 is shown bolted to the bars 31 and 38 for greater strength. The construction of the wall units and partition units provides for windows and doors, wherever there are windows and doors Wanted.

In Figure 8 the fioor section 46 having the bar inserts 41 projecting in vertical holes 48 is ready to be bolted to the wall section 49, having the ledge 50 as asupport for the floor section, and the upwardly projecting bar inserts 5| having the holes 52. The upper wall section 53 has the slots 54 with the downwardly projecting bar inserts 55 having the holes 56.

In connecting the three sections 46, 49 and 53, the fioor section 46 is lifted over the projecting bar inserts 5| and rested on the ledge 50, the inserts 5| will then project upwardly from the vertical holes 48 of the floor section 46.

The angle bar inserts 47 of the floor sections 46 are now bolted to the angle bar inserts 5|, the plaster finish 51 of the wall section 49 will now meet the plaster finish 58 of the ceiling (the under side of the floor section 46) at an angle of 45, the insulation is shown by the numeral 59.

The upper wall section 53 is now connected to the wall section 49 and the fioor section 46, by bolting the downwardly projecting bar inserts 55 to the inserts 5| of the wall section 49 and to the inserts 41 of the floor section 46. When the three sections are connected the wallboard 60 is secured to the lower end of the wall section 53, thereby concealing the different connections.

The different sections from the foundation 6| to the roof 62 are similarly connected through insert joint members as already described.

Figures 10, 11 and 12 show another form, the walls being formed of blocks 63, having the vertical grooves 64, 65 and 66 in the end surfaces. The block, having the vertical holes 61 and 68,- is covered with tar paper and tar felt and has on its front side a layer of cork insulation 69, said cork insulation being fastened to the surface of the block by the nails 70, bent as shown at 7| and laid in the cement while soft, a facing of plaster 12 or other material finishes the block.

The tar paper and tar felt 13 laid in the groove 14 seals the vertical holes at their upper end to form air cells when these blocks are laid on top of one another to form a wall section. This construction prevents condensation on the inside of the block.

In Figures 13 to 16 inclusive a modified form of the invention is shown in which the connecting bars 15 are connected together at their inner ends to form a reinforcing bar 16 formed of a straight middle portion 11 terminating in oblique portions 78. The unit is further strengthened by the rods 79 below and parallel to the middle sections 11.

In Figure 14 floor sections are connecting bars shown with the 15 projecting from pockets 8|].

The floor sections are completely made in the factory with the tile covering 8| or any other suitable surface.

The columns 82 have the reinforcing rods 83 with the link extensions 84 securely held thereto at one end and projecting in recesses 85 at the other.

The beams 66 reinforced with the bars 15 and rods 19 terminate in angular portions 86 provided with pockets 8? permitting access to the bars 15 which engage the adjoining beams through the holes 81.

The angular portions of the beams have recesses 88 for the links 84 projecting outwardly from the beams 86 and adapted to be bolted to the column above by the bolt 89.

Figures 17, 18 and 19 show a method of decreasing the weight of various units by forming hollow hexagonal pockets 96 the webs of which form a sort of honey comb construction. For greater strength or other considerations, the pockets can be made circular.

The construction of the floor unit 9| is very much similar to the construction of the wall unit illustrated in Figures 17 and 18 except for the reinforcing metal 92 covering the pockets and attached to the unit for the ceiling.

It is easily understood that a great number of modifications can be made to the various units, they can be made to represent elaborate masonry as shown in Figure 9. The units can be of various shapes and sizes such as the arches 9|, the foundation walls 92, the railing 93, the wall sections 94 and the roof sections 95.

What I claim is:-

1. In truss beams, a series of beams having their ends tapered and pointed to a common center and abutting each other on the surfaces of the tapered end and having transverse apertures spaced intermediate of the length of the tapered ends and on the tapered surfaces communicating with the apertures of the abutting beams, coupling bars having flattened ends longitudinally set and bared from the tapered surfaces and projecting into the facing apertures and overlapping therein the coupling bars projected from the opposite beam, and bolts joining the ends of the overlapping coupling bars and incidently locking the abutting beams.

2. In truss beams, a series of beams having their ends tapered and pointed to. a common center and abutting each other on the surfaces of the tapered end and having transverse apertures spaced intermediate of the length of the tapered ends, and on the tapered surfaces communicating with the apertures of the abutting beams, coupling bars having flattened ends longitudinally set and bared from the tapered surfaces and projecting into the facing apertures and overlapping therein the coupling bars projected from the opposite beam, bolts connecting the ends of the overlapping coupling bars, vertical bars anchored in the end of the said beams and projecting from the upper and lower surface thereof, columns having their corners bared, coupling bars in said columns having their ends exposed in the bared corners and overlapping the projecting anchor bars and bolts connecting the overlapped bars.
